Reference photos for these sketches can be found on an amazing motorcycle ride report:

A young couple from Estonia took a motorcycle trip around the world.  It took them several years, and they kept a blog on the Adventure riders website.  Margus and Karlina traveled 170,000 km over 1,126 days, and traveled through 70 countries.  The photographs are what dazzled me – the quality, and the content – they have fantastic images of people, places and things they encountered.  I do not presume that my sketches are anywhere close to the quality of their photos, just that I was touched by them.  So, here are a couple – just a start.  I received their permission to post these.
If you have some time, stop by and read their report – you won’t be bored!
